A69-year-old diabetic man without previous cardiac history was admitted for stabilization of glycemic control. A routine ECG showed atrial fibrillation with right bundlebranch block, and the chest radiograph revealed marked prominence of the central pulmonary arteries. Accordingly, transthoracic echocardiography was performed, which demonstrated an atrial septal defect with moderate pulmonary h...

A9-year-old girl underwent transesophageal echocardiography (TEE) to determine whether there was an indication for transcatheter closure of her secundum atrial septal defect (ASD). She had been diagnosed as having a single defect by transthoracic echocardiography at 6 months of age. During previous clinic visits, her parents often complained that she had occasional episodes of central cyanosis,...

We read the article published by Laguna et al with interest. However, in the wake of that reading, we would like to make a few comments that we believe to be important. The sinus venosus forms part of the right atrium during embryonic development. Over the course of this period, the left cusp of the sinus venosus valve is incorporated into the septum secundum, whereas the right cusp gives rise ...

BACKGROUND The Eustachian valve (EV) is an embryonic structure redirecting the blood flow from the inferior vena cava through the foramen ovale. It may persist in adults as a floating membrane in the right atrium. A large EV can be associated with thrombosis, embolization, bacterial endocarditis, etc. The prevalence of EV in the normal population is unknown. AIM to assess the prevalence and s...

was taken which showed that the aneurysm had increased in size (Figure 1D). Faced with a risk of complications (thrombosis, embolism, rupture) we decided to perform another surgical procedure involving aneurysm resection and derivation of the internal mammary artery to the anterior descending artery (Figure 2). The microbiology culture was sterile and the histological study showed non-specific ...

The Chiari network is described as a reticulated network of fibers connected to the Eustachian valve identified as the embryological remnant of the right valve of the sinus venosus. It is an incidental finding without any significant pathophysiological consequences. However, the presence of the Chiari network in the right atrium obliges the physician to differentiate from other right atrial pat...
